论文摘要
我们通过实验表明，通过使用767 nm处的单个激光器，通过虚拟水平通过虚拟水平来证明从6S1/2接地状态到7d3/2,5/2激发态的剖宫腔型四极杆过渡。激发的状态能级种群的特征是改变激光功率，蒸气的温度和激光束的极化组合。对于高分辨率过渡间隔识别，获得了优化的实验参数。 7d3/2,5/2的磁偶极耦合常数A和电二极耦合常数B通过使用超级NE级别的间隔来精确确定。结果a = 7.39（0.06）MHz，b = -0.19（0.18）MHz对于7d3/2状态，a = -1.79（0.05）MHz，b = 1.05（0.29）MHz的7D5/2状态与先前报道的结果相吻合。这项工作对确定原子结构信息和奇偶校验不保守是有益的，这为精确测量和原子物理学的领域铺平了道路。
We experimentally demonstrate the cesium electric quadrupole transition from the 6S1/2 ground state to the 7D3/2,5/2 excited state through a virtual level by using a single laser at 767 nm. The excited state energy level population is characterized by varying the laser power, the temperature of the vapor, and the polarization combinations of the laser beams. The optimized experimental parameters are obtained for a high resolution transition interval identification. The magnetic dipole coupling constant A and electric quadrupole coupling constant B for the 7D3/2,5/2 states are precisely determined by using the hyper ne levels intervals. The results, A = 7.39 (0.06) MHz, B = -0.19 (0.18) MHz for the 7D3/2 state, and A = -1.79 (0.05) MHz, B =1.05 (0.29) MHz for the 7D5/2 state, are in good agreement with the previous reported results. This work is beneficial for the determination of atomic structure information and parity non-conservation, which paves the way for the field of precision measurements and atomic physics.
